Spatial vicinity is a kind of important correlation due to the First Law of Geography [1]}. Adjacent regions in space are naturally more similar. According to Equation REF , through topology analysis, the geographic neighborhood dataset \(N\)  contains geographic neighborhood vector \(\overrightarrow{n_i}\)  for each urban region \(r_i\) . These vectors actually represent vicinity correlations among regions. Hence, the vicinity correlations can be described as:
\(V C^{i j}={simi}\left(\overrightarrow{n_{i}}, \overrightarrow{n_{j}}\right)\)
